1. Grateful Dead

The original jam band, Jerry Garcia and company never played the same show twice. This is why they were followed all over the world by “Deadheads." They would play a different set every night, which led to fans attending as many shows as possible in order to hear what they wanted. People started following the band from city to city. So unique were the shows, Deadheads began to trade bootlegged live recordings — the first "illegal downloading," if you will. Deadheads don’t remember many Grateful Dead moments. The traveling carnival that was a Dead tour could have supplied about 8,000 Woodstocks with all the mind-altering substances they needed. How high do you have to be to invent tie-dye? The answer: Grateful Dead high. The original lineup stopped touring in 1995, but with over 130 albums released, there’s enough to go around for a couple more generations of Deadheads.
